In order to increase the accuracy of the results in thermometers and temperatures, can't we say using a sensitive thermometer or using a larger scale of reading? Why is it wrong to say so??
You can also include how much should It be immersed in the the apparatus, that it shouldn't touch the bottom or beaker or be immersed in the liquid which might give us wrong reading 'cause there might be few impurities present in the liquid.In order to increase the accuracy of the results in thermometers and temperatures, can't we say using a sensitive thermometer or using a larger scale of reading?

http://papers.xtremepapers.com/CIE/Cambridge International O Level/Physics (5054)/5054_s10_qp_42.pdfThat sensitivity point is correct.. i think, but not the range one!
You can say avoid parallax error, by looking perpendicularly to the reading.
conguctors cannot be charged by friction becuz the electros can move through thm and rearrange thm self...?is this correct....
2nd and 5th options are correcthttp://papers.xtremepapers.com/CIE/Cambridge International O Level/Physics (5054)/5054_s10_qp_42.pdf
check out qs1 part e both are wrong

question 4 part aWhich question?
red one's the string.can u explain which of the instruments have u used other than the newton meter
question 4 part a
Isn't the diagram given in the Mark Scheme?question 4 part a
no there is no diagram given in mark scheme .Isn't the diagram given in the Mark Scheme?
Apparatus: Clamp stand, thin cotton, iron bar, magnet, newton meter
Explanation:
The Iron Bar is tightened in the clamp stand and the magnet A is suspended vertically from the newton meter using a cotton loop. The magnetic pole at the lower end of the the magnet A is placed in contact with the iron bar and the newton meter is pulled slowly upwards. Note down the reading shown on the newton meter just before it is detached from the iron bar.
Repeat the above steps with the magnet B and compare the readings of the newton meter. The magnet which produces the larger reading on the newton meter is the strongest magnet.
ok waitno there is no diagram given in mark scheme .
btw thanku
thanku for itni mehnatok wait
I'll draw to draw one in paint and send it to you
gimme few mins
sure am waitng
